(1 + i)/(1 + 2i)

To simplify this, we need to multiply both sides by the conjugate.

(1 + i)(1 - 2i)

1 - 2i - i - 3i^2

Combine like terms.

3i^2 - 3i + 1

i^2 = -1

-3i - 2 is the simplified numerator.

(1 + 2i)(1 - 2i)

1 - 2i + 2i - 4i^2

1 - 4i^2

i^2 = -2

1 + 4

<h3><u>The simplified expression is ((-3i)/5) + ((-2)/5)</u></h3>

luis spent 8.75 on snacks at a basketball game. candy costs 1.25$ per package and chips cost .50$. Luis bought 10 snacks how man

ale4655 [162]

Answer:

Luis bought 5 packages of candy and 5 bags of chips

Step-by-step explanation:

1.25 for candy

0.50 for chips

1.25c + 0.50c = 8.75

First I tried to see how many times I could multiply 1.25, the answer that made the most sense was 5 because not only is 5 + 5 = 10, but when it equals the amount of money. So I changed my equation:

1.25(5) + 0.5(5)

6.25 + 2.5 = 8.75
